SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to all The Boeing Company Model
737 series airplanes. The NPRM
published in the Federal Register on
March 1, 2019 (84 FR 6981). The NPRM
VerDate Sep<11>2014
16:11 Jul 22, 2019
Jkt 247001
was prompted by a report that structural
fatigue cracks can develop in certain
aluminum pressure module check
valves prior to the design limit. The
NPRM proposed to require an
inspection to determine the part
numbers of the four hydraulic systems
A and B pressure module check valves
and applicable on-condition actions.
The FAA is issuing this AD to address
structural fatigue cracks in certain
aluminum pressure module check
valves, which could cause separation of
the check valve head from the check
valve body when hydraulic pressure is
applied, resulting in injuries to
maintenance personnel.
Comments
The FAA gave the public the
opportunity to participate in developing
this final rule. The following presents
the comments received on the NPRM
and the FAA’s response to each
comment.
Support for the NPRM
Two commenters supported the
NPRM. United Airlines (UAL) agreed
with the need for the NPRM. A private
citizen also expressed support for the
NPRM, but added that cost should not
be an issue in relation to airplane safety,
the cost of the proposed rule is
especially low, and that the FAA has an
ethical duty to protect the public by
adopting the proposed rule.
Effect of Winglets on Accomplishment
of the Proposed Actions
Aviation Partners Boeing stated that
the installation of winglets per
Supplemental Type Certificate (STC)
ST00830SE or STC ST01219SE does not
affect the accomplishment of the
manufacturer’s service instructions.
The FAA agrees with the commenter
that STC ST00830SE and STC
ST01219SE do not affect the
accomplishment of the manufacturer’s
service instructions. Therefore, the
installation of STC ST00830SE or STC
ST01219SE does not affect the ability to
accomplish the actions required by this
AD. The FAA has not changed this AD
in this regard.
Request To Change Applicability of the
NPRM
UAL requested that the FAA change
the proposed applicability from
including all The Boeing Company
Model 737–8 and 737–9 airplanes, to
use the effectivity specified in Boeing
Special Attention Requirements Bulletin
737–29–1126 RB, dated October 2, 2018,
which specifies The Boeing Company
Model 737–8 and 737–9 airplanes, line
numbers 5602 through 7050. UAL
PO 00000
Frm 00004
Fmt 4700
Sfmt 4700
mentioned that Boeing Special
Attention Service Bulletin 737–29–
1126, dated October 2, 2018, states that
‘‘Airplanes after line number 7050
cannot use Parker check valves as an
optional part,’’ and that this statement is
counter to the applicability stated in the
NPRM. UAL stated the understanding of
this statement to be that The Boeing
Company Model 737–8 and 737–9
airplanes, line number 7051 and later
were delivered without part number (P/
N) H61C0552M1; that the illustrated
parts catalog (IPC) does not authorize
installation of that part after delivery;
and that omission from the IPC should
ensure unapproved parts are not
installed on The Boeing Company
Model 737–8 and 737–9 airplanes, line
number 7051 and later; therefore
providing an acceptable level of safety.
The FAA disagrees with the request to
change the applicability of this AD. The
FAA does not control or approve the
Boeing IPC, and P/N H61C0552M1 is
considered a rotable part. Therefore, the
FAA has determined that these parts
could later be installed on airplanes that
were initially delivered with acceptable
parts, making those airplanes subject to
the unsafe condition. The FAA has not
changed this AD in this regard.
Conclusion
The FAA reviewed the relevant data,
considered the comments received, and
determined that air safety and the
public interest require adopting this
final rule as proposed, except for minor
editorial changes. The FAA has
determined that these minor changes:
• Are consistent with the intent that
was proposed in the NPRM for
addressing the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM.

Authority for This Rulemaking
Title 49 of the United States Code
specifies the FAA’s authority to issue
rules on aviation safety. Subtitle I,
section 106, describes the authority of
the FAA Administrator. Subtitle VII:
Aviation Programs, describes in more
detail the scope of the Agency’s
authority.
The FAA is issuing this rulemaking
under the authority described in
Subtitle VII, Part A, Subpart III, Section
44701: ‘‘General requirements.’’ Under
that section, Congress charges the FAA
with promoting safe flight of civil
aircraft in air commerce by prescribing
regulations for practices, methods, and
procedures the Administrator finds
necessary for safety in air commerce.
This regulation is within the scope of
that authority because it addresses an
unsafe condition that is likely to exist or
develop on products identified in this
rulemaking action.
This AD is issued in accordance with
authority delegated by the Executive
Director, Aircraft Certification Service,
as authorized by FAA Order 8000.51C.
In accordance with that order, issuance
of ADs is normally a function of the
Compliance and Airworthiness
Division, but during this transition
period, the Executive Director has
delegated the authority to issue ADs
applicable to transport category
airplanes and associated appliances to
the Director of the System Oversight
Division.
Regulatory Findings
This AD will not have federalism
implications under Executive Order
VerDate Sep<11>2014

13132. This AD will not have a
substantial direct effect on the States, on
the relationship between the national
government and the States, or on the
distribution of power and
responsibilities among the various
levels of government.
For the reasons discussed above, I
certify that this AD:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866,
(2) Will not affect intrastate aviation
in Alaska, and
(3) Will not have a significant
economic impact, positive or negative,
on a substantial number of small entities
under the criteria of the Regulatory
Flexibility Act.

SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to all The Boeing Company
Model 737 series airplanes. The NPRM published in the Federal Register
on March 1, 2019 (84 FR 6981). The NPRM was prompted by a report that
structural fatigue cracks can develop in certain aluminum pressure
module check valves prior to the design limit. The NPRM proposed to
require an inspection to determine the part numbers of the four
hydraulic systems A and B pressure module check valves and applicable
on-condition actions.
The FAA is issuing this AD to address structural fatigue cracks in
certain aluminum pressure module check valves, which could cause
separation of the check valve head from the check valve body when
hydraulic pressure is applied, resulting in injuries to maintenance
personnel.
Comments
The FAA gave the public the opportunity to participate in
developing this final rule. The following presents the comments
received on the NPRM and the FAA's response to each comment.
Support for the NPRM
Two commenters supported the NPRM. United Airlines (UAL) agreed
with the need for the NPRM. A private citizen also expressed support
for the NPRM, but added that cost should not be an issue in relation to
airplane safety, the cost of the proposed rule is especially low, and
that the FAA has an ethical duty to protect the public by adopting the
proposed rule.
Effect of Winglets on Accomplishment of the Proposed Actions
Aviation Partners Boeing stated that the installation of winglets
per Supplemental Type Certificate (STC) ST00830SE or STC ST01219SE does
not affect the accomplishment of the manufacturer's service
instructions.
The FAA agrees with the commenter that STC ST00830SE and STC
ST01219SE do not affect the accomplishment of the manufacturer's
service instructions. Therefore, the installation of STC ST00830SE or
STC ST01219SE does not affect the ability to accomplish the actions
required by this AD. The FAA has not changed this AD in this regard.
Request To Change Applicability of the NPRM
UAL requested that the FAA change the proposed applicability from
including all The Boeing Company Model 737-8 and 737-9 airplanes, to
use the effectivity specified in Boeing Special Attention Requirements
Bulletin 737-29-1126 RB, dated October 2, 2018, which specifies The
Boeing Company Model 737-8 and 737-9 airplanes, line numbers 5602
through 7050. UAL mentioned that Boeing Special Attention Service
Bulletin 737-29-1126, dated October 2, 2018, states that ``Airplanes
after line number 7050 cannot use Parker check valves as an optional
part,'' and that this statement is counter to the applicability stated
in the NPRM. UAL stated the understanding of this statement to be that
The Boeing Company Model 737-8 and 737-9 airplanes, line number 7051
and later were delivered without part number (P/N) H61C0552M1; that the
illustrated parts catalog (IPC) does not authorize installation of that
part after delivery; and that omission from the IPC should ensure
unapproved parts are not installed on The Boeing Company Model 737-8
and 737-9 airplanes, line number 7051 and later; therefore providing an
acceptable level of safety.
The FAA disagrees with the request to change the applicability of
this AD. The FAA does not control or approve the Boeing IPC, and P/N
H61C0552M1 is considered a rotable part. Therefore, the FAA has
determined that these parts could later be installed on airplanes that
were initially delivered with acceptable parts, making those airplanes
subject to the unsafe condition. The FAA has not changed this AD in
this regard.
Conclusion
The FAA reviewed the relevant data, considered the comments
received, and determined that air safety and the public interest
require adopting this final rule as proposed, except for minor
editorial changes. The FAA has determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
The FAA reviewed the following service information.
Boeing Special Attention Requirements Bulletin 737-29-1123
RB, dated October 2, 2018.
Boeing Special Attention Requirements Bulletin 737-29-1126
RB, dated October 2, 2018.
Boeing Special Attention Requirements Bulletin 737-29-1127
RB, dated October 8, 2018.
The service information describes procedures for an inspection to
determine the part numbers of the four hydraulic systems A and B
pressure module check valves and applicable on-condition actions. On-
condition actions include replacement of Parker pressure module check
valves, P/N
[[Page 35289]]
H61C0552M1, with Crissair pressure module check valves, P/N 1C4196.
These documents are distinct since they apply to different airplane
models.
This service information is reasonably available because the
interested parties have access to it through their normal course of
business or by the means identified in the ADDRESSES section.
Costs of Compliance
The FAA estimates that this AD affects 1,747 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspection for Parker pressure module 1 work-hour x $85 per $0 $85 $148,495
check valves, P/N H61C0552M1. hour = $85.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary on-
condition actions (per check valve replacement) that would be required.
The FAA has no way of determining the number of aircraft that might
need these on-condition actions:
Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
Cost per

------------------------------------------------------------------------
2 work-hours x $85 per hour = $170.... $6,652 $6,822
------------------------------------------------------------------------
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII: Aviation Programs,
describes in more detail the scope of the Agency's authority.
The FAA is issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701: ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to transport category airplanes and
associated appliances to the Director of the System Oversight Division.
Regulatory Findings
This AD will not have federalism implications under Executive Order
13132. This AD will not have a substantial direct effect on the States,
on the relationship between the national government and the States, or
on the distribution of power and responsibilities among the various
levels of government.
For the reasons discussed above, I certify that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Will not affect intrastate aviation in Alaska, and
(3) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
